ROAD-DRAG.

No. 924,31 1. Specification of Letters Patent. Patented June 8,1909.Application filed January 7, 1909. Serial No. 471,196.

To all whom it may concern: the drawings. The T-bar 6 has its base Be itknown that I, DAVID C. BOYD, citizen flanges 7 cut away at the ends toform end of the United States, residing at Galion, in recesses 8, thevertical flange being left to the county of Crawford and State of Ohio,constitute end tongues to which the vertihave invented certain new anduseful Imcally extending ortions of the actuating provements inRoad-Drags, of which the folarms 9 are pivotal y connected, the saidarms lowing is a specification. eing arranged in two pairs front andrear,

is invention comprehends certain new and the arms of the respectivepairs embracand useful improvements in road scrapers or ing the tongueas shown. The horizontally leveling devices, and the invention hasforits extending portions of the arms 9 roject in object an improvedconstruction of devices opposite directions and are bolted orothen ofthis character, embodying pivoted blades wise secured to the angle bars3 near the midthat may be tilted to different inclinations, dle part ofthe latter. The upper ends of the as well as a novel and efficientmechanism for front and rear airs of arms 9 are connected tilting theblades and for holding the same at together by a l ongitudinallyextending bar the desired inclined positions. 10. A rack 11 is securedin any desired way With this and other objects in view, as will to theside of the connecting bar 10, and a more fully appear as thedescription prospur pinion 12 meshes with said rack. The ceeds, theinvention consists in certain conpinion 12 is secured to a verticallydisposed structions, arrangements, and combinations operating rod 13which is provided at its upof the parts that I shall hereinafter fullyper end with a hand wheel or other device by describe and claim. whichit may be easily turned, and which is For a full understanding of theinvention, ournaled intermediate of its ends in a shaft reference is tobe had to the following desupporting bar 15. This shaft supportingscription and accompanying drawings in bar 15 is secured at its ends toapproxiwhich: mately U-shaped brackets 16, supported by Figure 1 is aperspective view of my imand secured to the platform or framework ofproved road drag or eveling device: Fig. 2 is the device. a top planview thereof: the actuating shaft 17 designates the platform of thedevice, or rod thereof being shown in section Fig. 3 the platform beingmade preferably in two is a longitudinal sectional view on the linesections at opposite sides of the single interof Fig. 2; and, Fig. 4 isa detail perspecmediate beam 6, and being formed of any tive view of theintermediate beam of the desired material or any desired constructionframework. or design, and the lower end of the o erating Correspondingand like parts are referred rod 13 may be journaled in one of tie plattoin the following description and indicated form sections or on one ofthe base flanges of the T-bar 6.

in all the views of the accompanying draw- From the foregoingdescription, in connecings by the same reference characters.

In the present embodiment of the invention with the accompanyingdrawings, it is manifest that the b ades 1 and 2 may be tion, myimproved road leveler or drag comtilted to any desired inclination byturning prises a forward blade 1 and a rear blade 2, V the same beingbolted or otherwise secured to the operating rod 13, which through theinstrumentality of the pinion 12 and rack 11 the front sides oftransversely extending I T-bars 3. A plurality of angular brackets 4will move the connecting bar 10 in one direction or the other to actuatethe arms 9 and are bolted or otherwise secured to the horizontallyextending flanges of the T-bars 3, tilt the blades.

In order to hold the blades either vertical one pair of brackets foreach bar, and the vertlcally extending portions of said angle or in anydesired inclination, the operating rod 13 carries at its lower end adetent wheel 1 brackets are pivotally connected by bolts or 18, and adetent or pawl 19 is pivotally similar fastenin devices to thelongitudinally extending beams 5 of the framework of mounted upon oneside of the vert cally extending flange of theT-bar 6, said detent beingsaid apparatus. The said framework embodies, in addition to the lonitudinally exprovided with an angularly disposed nose 20 designed to drointo any of t 1e notches of tending end beams 5, a single ongitudinallyextending intermediate beam 6 which is in the detent whee 18,1t bemgunderstood that the form of aT-bar, as clearly illustrated in theforward engaging end of the pawl 19 overbalances the rear end so as toavoid the necessity of using s rings. The rear end of the detent islatera ly extended as indicated at 21 and is somewhat broadened to forma foot treadle, so that the operator may readily depress the rear end ofthe detent and disengage the front thereof from the detent wheel 18.

The draft chains 2 or similar devices for drawing my road leveler overthe roads may be secured to the framework of the device in any desiredway.

Having thus described the invention, what is claimed as new is: I

1. A road drag, comprising a supporting framework, embodying a pluralityof longitudinally extending beams, blades having pivotalconnectionbetween said beams, actuating arms connected to said bladesand fulcrumed intermediate of their ends to one of the beams, aconnecting bar pivotally secured to said actuating arms above thefulcrum points thereof, a rack carried by said connecting bar, a pinionmeshing with said rack, and a vertically extending rod journaled on theframework, the pinion being carried by said rod.

2. A road drag, comprising a plurality of blades, a plurality oflongitudinally extending beams, to the end ones of which said blades arepivotally connected, actuating arms connected to said blades, andfulcrumed intermediate of their ends to the intermediate beam, aconnecting bar pivotally connected to the actuating arms above thefulcrum points thereof, a rack bar carried by the connecting bar, avertically CllSliOSGCl operatlng rod, a supporting bar in w nch said l l1 l l operating rod is journaled, and a pinion carried by said operatingrod and meshing with said rack bar.

3. A road drag, comprising a supporting framework, blades pivotallyconnected to said framework, said framework embodying end beams, asingle intermediate beam consisting of a T-bar, said T-bar having itsbase flanges cut away at the ends whereby to form end tongues, actuatingarms operatively connected to the blades arranged in front and rearpairs embracing and pivotally connected to said end tongues, meansconnecting together the front and rear actuating arms at the upper endsthereof, and m ans for swinging said arms whereby to tilt the blades.

i. A road drag, comprising a supporting framework, blades pivotallyconnected to W said framework, actuating arms fulcrumed on saidframework, operatively connected to said blades, a connecting barsecured to the actuating arms, a rack carried by said connecting bar, avertically disposed operating rod journaled on the framework, a pinionsecured to said red and meshing with said rack bar, a detent wheelsecured to said rod and meshing with said rack bar and formed withnotches, and a detent pivoted on the fran'rework and formed at one endwith a nose to engage the detent wheel, said detenr being formed at itsother end wit h a treadle. in testimony whereof l allix my signature inpresence of two witnesses.
